What is the issue?

I don't know how to explain this exactly, but when I try to run ollama run Llama3.1 I get the confusing error:

Error: a model with that name already exists

And it does exist, but the issue is that the casing is different (it's llama3.1, not Llama3.1). This is evidently confusing the engine somehow. If I give the lowercase version then its fine and loads normally, and if I give a name that doesn't exist then I get Error: pull model manifest: file does not exist.

This is running on Ubuntu 24.04, x64.
